GAUGE MEANS FOR FITTING SCREENS TO CARD CYLINDERS Filed April 20. 1950 2 Sheets-Sheet 2 Patented Sept. 22, 1953 "iZi 3 IGAUGE ,FCPR FITTING SCREENS'ITQ CARD CYLINDERS Ol n Elliott en lc, S-aG- n i c tiunnprilzfl, 1950, Serial matron This invention relates to a gauge means for fitting a screen to the main cylinder of a-carding machine and it is an object of'the invention to provide such a means whereby the desired curvature of a screen and of the clothingmay be accurately determinedwith'respect to the circumference of the cylinder.

Furthermore, it is an object of the-invention to provide a means of thiskind including two gauging elements, one for use with the said clothing and the second for direct use with the screen or screens to be fitted about-theperipher-y-o'f the cylinder from'one-or both ends of said clothing and wherein the setting of the second gauging element is madedirectly from the first gauging element.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my inproved means for fitting a screen asaforesaid whereby-certain advantages are attained, as will "be hereinafter more fully set forth.

In order that my invention may be better understood, I will now proceedto describe :the same with reference to the accompanying drawings, wherein: I

Figure 1 is a fragmentary diagrammatic :view in end elevation showing an initial stepinthe fitting of a screen to the main cylinder;

Figure 2 is a view in side elevation of the two gauging elements, illustrating the-settings ef -one gauge from the other;

Figure 3 is a view in top plan of Figure 2 Figure 4 of an enlarged sectional view taken substantiallylon the line i4 ofli'igure 3,;

Figure 5 is a sectional View taken substantially n'the line 5 -5 of Figure 4 and Fi u 9 e rartly insert o ndzrartly in e vat n i s ratinstb ste o p n a au n m m e o a screen for sett hesame- As illustrated in the accompanying drawings, A denotes a conventional type of main cylinder of a carding machine, around the upper periph-. eral portion .of which the usual clothing (not shown) is disposed to cooperate with the teeth on the periphery of the cylinder for the straightening out and laying of the fibers to be carded parallel as they pass between the clothing and the cylinder. Associated with cylinder A and applied clothing are the usual screens D, generally two in number and which, when in use, are supported in close proximity to the ends of the clothing and from below the cylinder A. As these several parts are well known and form no particular part of the invention, it is not believed that a-mor-e detailed descriptionorillustration'is necessary.

The fitting of a screen D is important when applied in connection witha new clothing after it has been installed relatively to the cylinder.

The invention as herein comprised involves two steps for determining-the arc of curvature -first; of the applied clothing-and, second, preforming the screens D accordingly, which can readily be accomplished by pounding-as required.

To put the method into efiect, twogauging elements X and Y are employed, the element X being used directly in connection with the applied clothing B and the element Y-being directly used inconnection with the screen D to be fitted.

The gaugingelement Y is of a length closely approximating the length of-a screen Das illustrated in Figure 6 of the drawings. The element Y as herein disclosed is longitudinally disposed on a segment of a circle. The extremitiesof the body :I are provided with the relatively long heads of duplicate structurebothas to form and dimensions and these heads 2 extend laterally and outwardly from the body I from the out-bow side of the'body I. 'Ihe'outerfaces 3 are smooth and unobstructed and outwardly-curved from end to end or in a direction lengthwise of the body I of the element These arcuate out-bow faces 3 are also of'the same radius and substantially the same radius as the applied clothing.

Freely disposed through the body I at a point between the heads 2 is an elongated shank i providedat its outer extremities with anenlargement or button 5. interposed between the enlargement or button 5 and the adjacent portion of the member ;I is an expansible member l; herein disclosed as a coil spring of-required tension surrounding the outerportion of the shank 4. This expansible member or spring 6 serves to constantly urge the shank 4 toward the limit of its normal outward movement. This normal position-ofthe shank 4 is determinedby contact of the member I, with the stop member I fixed to andsurrounding the shank A inwardly of the member I.

The shank 4 is passed through the center of the element l and the stop member I and is threaded at its inner end as at 3, which end engages with a socket 9, in the central portion of an elongated block III, the longitudinal axis of which is disposed lengthwise of the member I. The block II) is held against swinging or turning movement around the end portion 8 of the shank 4 by a pair of spaced pins I l projecting in parallel relation from the inner face of the member I and engaging in bores [2, opening through the block It. The pins H are at opposite sides of the shank A and equidistantly spaced therefrom with said pins ll freely and snugly engaged within the bores 12 opening through the block I0. Upon requisite turning of the shank 4, the block 10 may be adjusted, as desired, toward or from the body I for a purpose to be hereinafter explained.

The outer face 14 of the block is smooth and unobstructed and is disposed from end to end on an outward curvature or outbow of the same radius as the faces 3 of the heads 2.v

The element X is substantially the same dimensions as the element Y. The elongated body I5 is also arcuate or inbowed from end to end on its inbowed side and is provided at its extremities with the laterally directed heads l6 having their inner faces I! disposed from end to end of the heads is on a radius the same as the radius of the faces 3 of the heads 2 of the body I of the male gauge or element Y.

Freely disposed through the body is a shank l8 which is constantly urged toward and normally maintained at the limit of its outward movement by the expansible coil spring I9 encircling the shank !8 and interposed between an enlargement or button at the outer end portion of the shank [8. The normal outward position of the shank I8 is determined by the surrounding stop member 2! fixed to the shank l8 and contacting the adjacent inner face portion of the body !5 of the element X. The portion 22 of the shank i8 outwardly from the stop member 2! threads into a socket 23 arranged at the central portion of an elongated block 24. The longitudinal axis of the block 24 is disposed lengthwise of the body 15. At opposite sides of the socket 23 and equi-distantly spaced therefrom are the sockets or openings which snugly and slidably receive the parallel pins 25 carried by the body [5 to hold the block 25 against turning movement around the shank 18.

The outer face 2'! of the block 24 is also smooth and unobstructed and longitudinally curved on an inbow radius the same as the radii of the faces I! of the heads 16.

In fitting a screen D, a gauge element X is disposed circumferentially with respect to the cylinder A, with the faces I! of the heads it in close contact with the teeth on the periphery thereof. The shank 8 is then rotated in a direction to bring the face 21 of the block 24 into close engagement with the card clothing (Figure 1). After this adjustment of the gauge element X, the same is applied to the gauge element Y (Figure 2) with the faces 3 of the heads 2 of the element X in close contact with the faces II of the heads [6 of the element X. The shank 4 on the element Y is then rotated in a direction to bring the face M of the block it] into close engagement with the face 27 of the block 24 of the gauge element X. The gauge element Y is then transferred to the screen D (Figure 6) with 4 the element Y disposed lengthwise thereof. When the faces 3 of the heads 2 and I4 respectively of the element Y and block [0 have close contact from end to end with the inbow side or face of the screen D, said screen will be of required curvature for the desired fitting to the card cylinder A or as the case may be, to the clothing Y. When upon application of the gauge element Y to the inbowed side of the screen D, there is not the desired end to contact with the faces 2 and M, the screen D is to be pounded with a suitable implement until such desired contacts are obtained.

- It is of advantage to have the blocks I0 an 24 to one side of the longitudinal center of its body I or 15, respectively, as a finer adjustment of the screen D may be obtained. After a first fitting with the gauge element Y, said element may be reversed.

I claim:

- 1. Gauge means for checking the curvature of a screen of a carding machine with respect to the curvature of the applied clothing of the main cylinder of the machine, comprising two elongated elements of substantially the same length, laterally disposed and relatively long heads carried by the extremities of the elements, the outer faces of the heads being curved in a direction lengthwise of the elements, the curvatures of the two elements being of the same radius and substantially the same as the radius of the applied clothing, the arcuate faces of the heads of one element being on inbovvs and the arcuate faces of the heads of the second element being on outbows, blocks carried by the central portions of the elements at the same sides thereof as the heads, and means for moving each of the blocks toward or from its associated element, the outer face of each block being curved in a direction lengthwise of the associated elements on the same radius as the radii of heads and in the same direction of curvature.

2. In a means as set forth in claim 1, resilient means constantly urging the blocks toward the elements.

3. In a means as set forth in claim 1, parts for holding the blocks against displacing movement transversely of or across the element.
